Today I am going to outline the disadvantages of the Spiral Model. For last weeks blog I outlined the advantages so I hope some of you got a chance to read through that. Feel free to comment on that post or this post. Feedback is always welcomed.

Disadvantages of Spiral Model:

1) Costs are usually high when using this method.

2) It can be seen as a complicated approach especially for projects with a clear SRS (Software Requirements Specification).

3) To evaluate and review project, expert skills are required.

4) It is tough to follow protocols and rules properly throughout the duration of this model. However, it is required to effectively implement the Spiral Model.

5) It is not suitable for low risk projects.

6) Meeting budgetary and scheduling requirements is tough if this development process is followed.

I think the biggest disadvantage of the spiral model is when the model is used by small projects as there is no need to as the project is clear and concise and only puts added cost to the company as their is no need to use this method the waterfall model would be a way better choice
